Answer:
Step-by-step explanation:
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!
Answer:
During the interval 0 < x < 2, height of the water balloon is increasing.
Step-by-step explanation:
Graph of the linear function represents the height f(x) of a balloon over the time 'x' seconds.
There are three intervals of the time in which height of the balloon has been given.
1). In the interval of 0 < x ≤ 2, height of the water balloon is increasing (Since slope of the line is positive or the line is slanting upwards).
2). In the interval 2 < x ≤ 3, height of the water balloon is constant (Since slope of the line is zero).
3). In the interval 3 < x ≤ 4, height of the water balloon is decreasing faster. (Since the given line is slanting downwards).
4). In the interval 4 < x < 6, height of the water balloon is decreasing (Since the given line in this interval is slanting downwards).
Therefore, during 0 < x < 2, height of the water balloon is increasing.
Answer:
$329,375
Step-by-step explanation:
first take 155000 x 4.5% = 6975
take 6975 × 25 years = 174,375.
t or the total cost is 155,000 + 174,375 = $329,375
